Every natural body produces in their environment waste products: the trees – the leaves, snails – mucus, worms – humus deposits, etc., as a man, though. Moreover, the environment most significantly affected by the activities of this man, this is why the timely removal of garbage, the price of which often depends on various factors, is so important in large settlements. In modern cities you can find many different types of waste. Household waste is defined by its – a unique source of emergence. The activities of every individual containers overflowing with garbage, which are in all courts high-rise buildings. Rubbish, this is less dangerous than production, toxic it can not be, but the main problem of most cities today is the organization of timely removal of garbage to garbage value, enough to please every person living in the village. Often the cost of removal is too high due to need to resort to a considerable number of material handling and automotive equipment. Production.

The source of this garbage are the various branches of production. A characteristic feature of this collection is, above all, environmental harm and problem of disposal. When this production not continuous, and seasonal or short duration, is used to hire special garbage collection trucks and excavators lifts that will help take away a time to recycle all waste products. But at continuous production: processing metal factories of light industry, etc. Often, there is a transport, which is designed for such cases. Construction waste. When removal of construction debris for the city limits, are usually treated to a lease loading shovels and other handling equipment. This technique is very powerful, as waste on construction sites are unused and broken cement mixture bricks left over from demolished buildings and cutting iron fittings, which had been cut off. In the future, for reasons of overpopulation of our planet and the inability to determine the empty area for the transport of waste to be invented, perhaps a fundamentally new way of garbage collection – into space. That will have a sort of picture from space: the planet Earth, and all around this planet compacted rubbish – a pleasant enough! Therefore quite significant in urban areas problem, at least at the level of household waste, produce its components: packaging for food and even clothes, not from artificial substances, and natural product, which after its depreciation can easily rewrite our environment.

The residue is then warm above of 1000C with a reducing agent, occurring in this A stage the recycling of magnesium and zinc. It is treated, therefore, of a thermal process that consists of evaporating to the necessary temperature each metal to recoup it later, for condensation. Already the hidrometalrgico process generally operates the temperatures that do not exceed 100C. The used stacks are citizens to the previous milling, and later leached with acid sulphuric hidroclordrico or, following it purificao of the solutions through operations of precipitation or electrolysis for recovery of the magnesium zinc and dioxide, or cadmium and nickel. Many times the mercury is removed previously by heating.

Countries as Japan, France and Sweden use the known pirometalrgico process as Sumitomo (Japanese process), SNAM-SAVAM (French process) and Sab-Nife (Swedish process) for the reaproveitamento of stacks and batteries, however this process has a cost sufficiently raised, but it can be used for almost all the types of stacks. In Switzerland the process combines pirometalurgia, hidrometalurgia and is known as Recytec. It is used in the recycling of all the types of stacks and also fluorescent light bulbs and diverse pipes that contain mercury. The investment of this process is minor who Sumitomo, SNAM-SAVAM and Sb-Nife, however the operation costs are bigger. The Process American North of I CROWD (Pennsylvania, U.S.A.), known as Inmetco, was developed initially, with the objective of if recouping metallic poeiras proceeding from electric ovens. However, the process can be used to recoup also metallic residues proceeding from other processes and the stacks and batteries if they fit in these other types of residues.

Conclusion With the diverse problems caused for the inadequate discarding of stacks and batteries to the environment and for consequence to the human being, mainly observes it importance of abrangncia bigger in programs of collect and spreading in private institutions and public initiatives in the region rescuer metropolitan so that the population has easy access the points of delivery of these materials. Expositivas actions for a bigger consumption of the population of reloadable stacks also are viable, therefore this type of product has a bigger useful life of what excessively, thus diminishing the consumption of common stacks. It is of great importance the installation of companies specialized in the recycling process and/or reaproveitamento of stacks and batteries, thus stimulating more projects of collect, which had the biggest easiness of guiding of these materials for a recycling company. The creation of programs of Ambient Education for a bigger knowledge of the population on dangerous residues would be sufficiently viable, therefore with a bigger knowledge, the population could more intensively contribute in the correct destination of stacks and batteries. Moreover, a bigger fiscalization on the part of the public power to the manufacturers and deliverers become necessary so that all fulfill in severity the ambient legislation.

The Environment – a SERIOUS WORLD-WIDE CONCERN (the desertificao of lands) In the world exists ten deserts of extensive areas, however, these wild places have thousand of years, exhibited fertile lands, with forests and rivers and, obviously, had living beings. With inexorable passing of the time, of natural form, possibly had to the climate if to become drier, low rain precipitation, a hot region with ground arose half-barren or barren. With almost no vegetation, sand, dry, hot climate, without water, conditions of survival of the human being, exception of some animals that if adaptam to this new ecosystem. The originary term of Latin ' ' desertere' ' meaning abandonment, abandoned, surrounding hostile to the man. Desertificao is the process of ambient or climatic modification that leads to the formation of a barren landscape or a desert properly said.

(Dic. . Houaiss). We see then that the existing deserts had had its origin with the time and of form natural, in contrast of what he is occurring now, where the man is the main causer of this possible transformation. We have in Brazil, fertile, propitious considered land regions to the plantation of almost all the species of plants, however, areas northeast and South of Par seriously they are threatened of being transformed into deserts has long or average stated period, therefore currently they present a half-barren climate In the South of the Country, in Alegrete, increases known ' ' desert of pampas' ' , visible in the ASDs (Susceptible Areas to the Desertificao). The process of deforestation without limits, of uncontrollable form, with the target to remove wood, formation of pastures, culture of the sugar sugar cane, soy and other cultures, wrong behaviors of the man in the use of the ground, only generates improlferos effect. Manifest the degradation of the land, that is, consuming or exhaustion and gradual decomposition of the ground, harming biodiversity, which had not consentaneidade to the normal use of the land. The greed in the activities of mining, with the objective of precious metal extration, for in such a way, digging and dislocating the land without no positive planning. The forest fires are harmful to the environment, mainly in the period of the droughts, promoted for the canavieiros, aiming at cleanness of the sugar cane for the cut. The arsons and guilty devastam extensive areas of native and preserved forests. We are living deeply in the daily one, climatic changes of disordered form, long periods of dries, where the scarcity of rain cause many upheavals to the Brazilians, due to water lack. You will have preoccupying, currently we feel the consequncias of this recklessness, however, if the governmental bodies, not to take urgent and rigorous steps how much to the subject, rigid norms the respect, launching campaigns of orientation to the population in this direction, prioritizing for the prudence, who will suffer are our children and grandsons, therefore in a future not very distant, we will have a desolating picture, the new outbreak of many desert-like areas in Brazil.

To preserve the environment not makes individually and nor with an only attitude, the ambient preservation requires the effort of all, that can make the use of diverse forms for such end. The problem is that many times, us human beings, for not terms time or pure unfamiliarity, we leave to give our spontaneous contribution and finish for collaborating for the ambient destruction. It wants to make its part! Then they practise some of these good examples or all if will be able, thus will be with the clean conscience in relation to the environment. OF the EXAMPLE All citizen can inside collaborate with the environment giving the house example, either it, in its work, the street or in any place that is most important she is that an only place does not exist to exert the ambient preservation. The people HAVE COVERED ITS RIGHTS All have the right of living in a balanced environment. When to find any form of aggression to the environment, looks the local authorities and denounces, has covered its rights and fiscalize if they are being taken the had ones you provide. Perhaps this PREVENTS the CONSUMERISM is the best weapon that you have to defend the environment, the consumerism heats the engines of the industries stimulating them it each time more to make extrations of substances cousins of the environment and increasing the amount of generated solid residues in a place, therefore it only buys what you need. IT CULTIVATES the GREEN To cultivate the green it means to spread the green in all the parts that will be able, it plants a tree in its garden, plants a change of roses in the deep one of its yard, it plants gram instead of making sidewalk, it recoups the next forest its house, the more green the world to be better will be our quality of life.

Start this study appraising the words: ecology, environment, sociocultural, natural, social evolution and nature. According to site Wikipdia we have the following results: The Ecology is the science that studies ecosystems, that is, is the scientific study of the distribution and abundance of the beings livings creature and the interactions that determine its distribution. The interactions can be between beings livings creature and/or with the environment. The word Ecology has origin in the Greek ' ' oikos' ' , that it means house, and ' ' logos' ' , study. Soon, for extension it would be the study of the house, or more generic form, the place where if it lives.

The environment comumente called only environment, involves all the alive and not alive things occurring in the Land, or in some region of it, that they affect ecosystems and the life of the human beings and in the Conference of United Nations on the Environment celebrated in Estocolmo, in 1972, defined the environment of the following form: ' ' The environment is the set of physical, chemical components, biological and social capable to cause effect indirect right-handers or, in a short or long stated period, on the beings livings creature and the activities humanas.' ' Sociocultural evolution is a term-valise for theories of cultural evolution and social evolution, describing as cultures and society if they had developed through the time. The majority of the boardings of the century XIX and some of century XX objectified to supply models the evolution of the humanity as a whole, arguing that different societies are in different stages of the social development. No longer Aurlio dictionary has the following concepts on: Natural? that it belongs or that is mentioned to the nature, produced for the nature, or in accordance with its laws. Nature? set of the laws that preside over to the existence of the things and the succession of the beings.

Defined this concept, she is necessary to understand the interactions of the society with the same. The society has a good time adopted a life style where the priority is the personal accomplishment, it has it cost that will be, and the activities developed for the man tend to provoke some type of impact to the way. Today for influence of the media the definition of ambient impact this always on to a damage the nature. But, if the impact is an alteration of the environment provoked for the man, is important to stand out that this can or not to be beneficial. A simple example of a beneficial alteration would be the introduction of a professional corporation, where if the service of selective collection is spread out the receiving community. Treating to the adverse impacts to the environment, considering a company, it is important that all the stages of the cycle of life of an enterprise are taken in consideration. According to Sartori et al (2008), the industries of laticnios is manufacter units that process milk, producing the most diverse derivatives. In its work on the ambient management in industries of laticnios in Brazil, it Sanches cites (1997), affirming that some decades behind, the process of raw material transformation in products did not consider the adverse effect in ecosystems and the proper society, allowing that social and ambient problems emerged that each time more if become critics it welfare of the society. The process of improvement of milk generates a volume of effluent liquids three times at least bigger, from which more than 90% of this sum do not receive any type of treatment, SEBRAE/MG (1997,1998). In accordance with Fields et al (2004), this occurs because the majority of the laticnios, that are of small average transport, presents financial difficulties to keep specialized staff who has capacity to work with technological innovations and to operate systems of effluent.
